There numerous applications of coating, including drug layering, modified release coating, physical and chemical protection, aesthetic purpos identification of drugs. Various coating techniques from conventional pan coating to laser assisted solvent free techniques have bee...

Sym-triazines have been documented for their antitumor, antimicrobial and anti-cancer actions. The present work aims to derive a variety of 1,3,5-triaryl-1,3,5-hexahydrotriazine using ultrasound assisted reactions from the reactions of aryl amines with aqueous formaldehyde. Furthermore, a special study on the different solvents and revealed that mixture of water and ethanol was found to be the ...

It is demonstrated that oxidative debris can be separated and largely removed during the surfactant assisted phase transfer of graphene oxide from a water/ethanol mixture to dichlorobenzene. The new procedure described provides a facile method to obtain monolayer dispersed graphene sheets in a nonpolar solvent via solvothermal reduction of graphene oxide accompanied by an effective purification...

Traditional hydrodistillation (HD), steam distillation extraction (SD), organic solvent extraction (SE), and microwave assisted hydrodistillation (MWHD) techniques were compared and evaluated for their effectiveness in the isolation of essential oil of Melissa officinalis from Algeria. The microwave assisted hydrodistillation technique was optimized in terms of both delivered power and time dur...

An ethanol-assisted method is utilized to generate a robust gelated crystalline colloidal array (GCCA) photonic crystal sensor. The functionalized sensor efficiently diffracts the visible light and responds to various stimuli involving solvent, pH, cation, and compressive strain; the related color change can be easily distinguished by the naked eye.

A novel method is developed for template assisted fabrication of a regular assembly of microcavity arrays. Simple micropatterns on PDMS mold are used to create complex geometries via solvent vapor back pressure in a biodegradable polymer. Cavities are in turn replicated in complimentary PDMS mushroom like microstructures.

Mechanochemistry is maturing as a discipline and continuing to grow, so it is important to continue understanding the rules governing the system. In a mechanochemical reaction, the reactants are added into a vessel along with one or more grinding balls and the vessel is shaken at high speeds to facilitate a chemical reaction. The dielectric constant of the solvent used in liquid-assisted grindi...

The present work deals with comparison of microwave assisted extraction to that of conventional solvent extraction for the extraction of rice bran oil (RBO); focusing on extraction yield and oil composition. Microwave assisted extraction act as a green process over other method and proved that it is effective method for extraction of oil. The investigation also focuses on the study of functiona...

Microwave-assisted extraction of pectin from lemon peels by using ionic liquid as alternative solvent was investigated. The extracted pectin was detected by Fourier transform infrared spectra. The extraction conditions were optimized through the different experiments in conjunction with the response surface methodology. A pectin yield of 24.68 % was obtained under the optimal parameters: the ex...
